Insulation Characteristic Analysis of Coconut Oil and Palm Oil as Liquid Insulating Material
International Journal of Simulation: Systems, Science & Technology, 2016The paper presents a study which has been carried out to use coconut oil as insulation in transformers. In transformer, oil is used as a coolant and also as an insulator. Nowadays, petroleum based oil is widely used in the transformer as it meets the requirements to be the best insulator.

Bioremediation of insulating oils
IEE Colloquium Insulating Liquids, 1999Bioremediation is the process whereby naturally occurring micro-organisms are used to digest chemicals into harmless products such as carbon dioxide, water and microbial biomass. A wide range of chemicals can be degraded in this way including oils and greases.

Dielectric response of transformer insulation oils
2012 10th International Power & Energy Conference (IPEC), 2012Dielectric diagnosis with polarization and depolarization currents (PDC) which employs the dielectric response of system in time domain is applied to investigate differences between PDC patterns produced by two types of transformer insulating fluids, mineral and bio-degradable oil.

Insulating Oil for Underwater Oil Production Equipment
Chemistry and Technology of Fuels and Oils, 2003The problem of using electric insulating oils in underwater oil production equipment is examined. The results of comparative studies of the physicochemical and insulating properties and thermooxidative stability of domestic and foreign oils of this class are presented.

D-C cleanup in insulating oils
Electrical Engineering, 1935Three unusual types of behavior of insulating oils have been subjected to a series of experiments which indicate that all 3 are closely related. These types of behavior are the reduction of conductivity and a-c dielectric loss following a sustained application of continuous potential (called ``d-c cleanup''), the current-time relation under continuous ...

Journal of the Institution of Electrical Engineers - Part I: General, 1942
In this paper, an endeavour has been made to indicate the present position in this country of the insulating oils and compounds which are available for cables, and to describe their behaviour in impregnating plants.The oils are of the paraffinic and naphthenic types and either class may be used in oil-rosin compounds.

Reconditioning of Insulating Oils by Activated Alumina
Transactions of the American Institute of Electrical Engineers, 1939THE use of insulating oil in electrical equipment carries with it the problem of prevention of deterioration when the oil is subjected to elevated temperatures in the presence of air. Deterioration may be accelerated by the presence of moisture and organic acid. This condition is found in certain types of transformers and oil-filled bushings.

Oil stresses in impregnated-paper insulation
Electrical Engineering, 1945RECENT EXPERIMENT on fully impregnated cable-type paper insulation, has shown that under certain conditions use of a paper of low density results in a higher dielectric strength than does the use of a paper of higher density.1 It has also been shown that failure of such insulation usually begins in the oil channels between successive turns of paper ...
